Milwaukee Compression Spring
Model Number: 40-50-0930
The Milwaukee 40-50-0930 is a genuine OEM Compression Spring for use in compatible Milwaukee tools. Compression springs are helical coil springs that resist compressive force — storing energy when compressed and releasing it to push components apart or return them to their rest position. They are used throughout Milwaukee tool assemblies in applications such as forward/reverse selector detents, chuck jaw return mechanisms, depth stop returns, trigger returns, and clutch engagement assemblies. Each compression spring is wound to a specific wire diameter, coil diameter, free length, and spring rate that determines its force output at a given compression. A broken, set, or weakened compression spring that can no longer provide the correct return force or detent resistance requires replacement to restore proper mechanism function.
Using a genuine Milwaukee OEM compression spring ensures the correct wire diameter, coil count, free length, and spring rate for the mechanism it serves. Non-OEM springs may not match the original force characteristics, leading to improper mechanism function or premature fatigue failure. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct compression spring for your specific unit.
